BoostSocket/Level2Design

boost::socket Level 2

Provide restricted interfaces to reduce preconditons and avoid usage errors.

• AcceptorSocket concept - a socket that accepts connections
• DataSocket concept - a socket that can send and receive data
• Connector concept - a factory for actively connected data sockets

This should probably be imlementations of more general Acceptor, Connector and Data Connection concepts, that could also be implemented with pipes, etc.

• Acceptor concept - a passive communication endpoint that accepts connections

As mentioned by Boris Schaeling in http://article.gmane.org/gmane.comp.lib.boost.devel/12323 there are several io models that could be supported.

1. blocking
2. multiplexing
3. signal-driven
4. asynchronous

• Asynchrounous Acceptor concept - a communication endpoint that accepts connections asynchrounously
• Asynchrounous Socket concept - a socket that can send and receive data asynchrounously

multipelxing primitives

• AsynchProactor Concept - proactive multiplexing of events
• SocketReactor Concept - reactive multiplexing of events
